WEIGHING-MACHINE Specification of Letters Patent.

Patented July 9, 1907.

Application filed January 21, 1907. Serial No. 353,237.

To all whom it may concern.-

Be it known that l, ROBERT G. HOWARD, of Newton, county of Middlesex, State of Massachusetts, have invented au Improvement in Weighing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to weighing machines, and has for its object to provide a weighing machine with an advertising-device having a plurality of advertisements, which is adapted to be operated to'successively display the advertisements and the operation of which must be effected before the Weight of the person mounting or standing on the platform of the machine can be obtained.

My invention comprehends the employment of weighing -mechanism having an indicatingdevice which is movable back of a sight opening and which is adapted to be operated by a weight on the platform4 to display, at said opening, the correct weight, and a movable screen covering said opening, whereby the indicating-device is normally concealed, and an ad vertising-device having a plurality of advertisements and an operating-device for said advertising-device adapted to operate it to successively display the advertisements and also to operate said screen to uncover the sight opening, so that the weight on the indicatingdevice may be observed only when said advertisingdevice is operated.

Figure l shows in front elevation a weighing machine embodying this invention. Fig. 2 is an enlarged front elevation of the head of the machine, the front plate being broken away to expose the parts which are concealed by it. Fig. 3 is a rear side view of the head of the machine, the back plate being removed. Fig. 4 is a vertical section of the head of the machine taken on the dotted line 4 4 of Fig. 3. i

a represents the base of the machine, b the movable platform, c a column rising from the base a which contains the platform rod b, (l a circular or other shaped head which is mounted on the column c and which contains the operating parts of the weighing-mechanism and also of the advertising-device.

The platform rod b is connected at its upper end to a cross-bar b2, to which the lower ends of the weighing springs c, e, are attached, and the upper ends of said springs are attached to a cross-bar e, which is supported at the top of the head d. i

A rack-bar f is formed upon or erected on the crossbar b2, which extends upward, and its teeth engage a pinion f secured to a sleeve2 mounted on a shaft f2, having its bearings centrally disposed in the head d. A circular indicating-plate f3 is secured to the sleeve f2, having on its front face numerals designed to indicate the weight, and said indicating-plate is located back of a front plate j having a sight opening f5,

through which anyone of the numerals on the indicating-plate f3 are observable. When a person mounts the platform the indicating-plate will be turned and the numeral thereon, indicating the weight, will be brought into position back of the sight opening f5.

The mechanism thus far described is common in Weighing-machines and is herein shown merely for the sake of illustrating my invention, and l desire it to be understood that my invention comprehends the employment of any equivalent form of weighing-mechanism by which the Weight of the person standing on the platform maybe indicated through a sight opening. The advertising-device consists essentially of a disk g secured to a shaft gf having its bearings in the frame at a point above the shaft j 20, and said disk is located in the back part of the head and has printed or otherwise provided on its front side or face a plurality of advertisements. The head of the machine is provided with an extension g2 at the top, the front plate of which is formed with a display opening g3 for the advertisements, back of which the advertisements will be successively brought to view as the disk is turned. A toothed wheel g'? is secured to the shaft g/ having any desired number of teeth thereon, although preferably having as many teeth as there are advertisements on the disk g. An arm g5 is also arranged loosely on the shaft g bearing a pawl g adapted to engage the teeth of said wheel gl and which is held in engagement with said Wheel by a spring and said arm g5 is connected by a link g7 with a pivot ed lever gs which extends through a slot in the side of theihead and is provided at its outer end with a hand piece by which it may be depressed. A spring g" is attached to said lever which normally holds it in its elevated position or Whichreturns it to its elevated position when said lever is depressed. Depression of said lever operates to turn the advertising-disk to display the next advertisement of the series at the display opening. Another arm h is also mounted loosely on the shaft gf, bearing a pawl h/ which is held pressed into engagement with said toothed wheel gL by a spring, and said pawl carrying arm is connected by a link h2 with the pivoted lever gs. Depression of the lever g8, therefore, also operates to move the pawl carrying arm h in order that its pawl may engage the next tooth of the Wheel g4 preparatory to turning said wheel and thereby moving the advertising disk another step to display the next advertisement when the arm g8 is raised or lreturned to its normal elevated position.

A toggle comprising the pivotally connected members t' and il is connected at one end to the frame and at the other end to the actuating lever g8 and the spring 'F is attached to one of said members, as i for instance,

which acts to hold the toggle in a certain position to i llO An arm j is connected with the platform rod bearing at its extremity an upright pin j which is located beneath the member i and which is adapted to engage said member and raise it when the Weight is removed from the platform and the latter permitted to rise to thereby unlock the toggle and permit the actuating lever g8 to resume its normal position.

When the actuating lever is depressed by hand it will become automatically locked in its lowermost position and When the Weight is removed from the platform said locking-device Will be automatically released and the actuating-lever permitted to resume its normal elevated position; and the advertising-device Will be operated one step when the actuating-lever is depressed and another step when the actuating-lever is raised.

A plate or screen k is located back of the sight opening f5 and in iront ol`: the indicating disk, which conceals the numeral on said disk back of the sight opening, and said screen is secured to the shaft/f2 and is moved by said shaft to uncover the sight opening in order that the numeral indicating the Weight may be observed. The shaft f2 has an arm c/ secured to it which is connected by a link k2 with the actuating-lever g8. Depression of said actuating-lever g8 rocks the shaft f2@ and moves the screen.

Thus it Will be seen that when a person mounts the platform the indicating-plate Will be turned to bring the correct numeral indicating thc weight back o the sight opening, but in order that the person may observe the numeral indicating the Weight, the actuating-lever gs ol the advertising-device must be operated. Therefore, to obtain the Weight the advertising-device must be operated and a new advertisement presented to view at the display opening.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is1 A l. In a weighing machine, the combination of weighingmechanism connected with and operated by a movable platl'orm and having a movable indicator, a front plate having a sight opening back of which said indicator is located and also having a display opening, a screen located back of the sight opening, an advertising-device located back of said front plate having a plurality of advertisements adapted to be successively displayed at said display opening and means for operating said advertising-device to display a dilferent advertisement and also to move the screen to uncover the sight opening, whereby the indicator will be exposed only when the advertising device is operated, substantially as described.
